Detailed Description

template<typename FunctionObject, typename Result = void>
class ecl::NullaryFunctionCopy< FunctionObject, Result >

Create a NullaryFunction object composited from an existing function object.

Takes a nullary function object (strictly by definition) and creates a NullaryFunction child object. This is useful in utilising the inheritance from NullaryFunction (needed for slots and similar classes).

Template Parameters:

FunctionObject	: type of the function object to be wrapped.
R	: the return type.

FunctionObjects.

NullaryFunction child constructor for nullary function objects.

Creates a child of the NullaryFunction class by copying a nullary function object (one that is purely by definition).

Parameters:

f_o	: the function object to be assigned to the NullaryFunction child.

The nullary function object call.

Redirects the call to the composited nullary function object call.
